Embodiment Construction

[0012] Such as figure 1 In the shown system diagram, the solid line part is a schematic diagram of a general electric drive mining vehicle drive system, and the technical scheme of the present invention is as follows if the system constitutes figure 1 The dashed path. The energy-saving control system of the braking process of the electric drive mining vehicle in the present invention includes: engine, alternator, rectifier 1, 2, inverter 1, 2, 3, drive motor 1, 2, brake circuit breaker, brake Resistance, transmission cooling system.

[0013] Engine: the power source of the transmission system;

[0014] Alternator: converts the mechanical energy of the engine into electrical energy in the form of alternating current;

[0015] Rectifier 1: converts the alternating current of the alternator to direct current;

[0016] Inverters 1 and 2: convert the DC power into the AC power needed to drive the motors 1 and 2;

[0017] Drive motors 1 and 2: convert electrical energy into mec...

Abstract

The invention provides an energy-saving control system for braking process of an electrically-driven mining automobile, which comprises an engine, an alternator, a rectifier I, an inverter I, an inverter II, a driving motor I, a driving motor II, a brake circuit breaker, a braking resistor and a transmission cooling system. The control system further comprises a control loop for braking process; the control loop for braking process comprises a rectifier II and an inverter III. The control system provided by the invention saves the energy output of the engine by changing the vehicle energy transfer path and control mode during the braking process, so as to achieve the effect of energy conservation.

Description

technical field [0001] The invention relates to the braking field of an electric transmission mining vehicle, in particular to an energy-saving control system and method during the braking (slowing) process of an electric transmission mining vehicle. Background technique: [0002] The electric transmission mining truck is a large off-road transport vehicle. It is a heavy-duty dump truck used in open-pit mines to complete the tasks of rock and earth stripping and ore transportation. It goes to and from the mining point and unloading point. Its working characteristics There are continuous uphill and downhill conditions in the journey. [0003] The transmission system of the electric transmission mining vehicle is composed of a diesel engine, a generator and a driving motor. In the long-distance downhill process of electric drive mining vehicles, braking (slowing) is required. Generally, the kinetic energy of the vehicle is converted into electrical energy by converting the dr...
